Rootbound does exist.
cannabis has simply adapted to an indoor environment, a restricted environment. I started experimenting with this almost 3 years ago now.
At the time i thought i was onto something new.. and i mistakingly went on to believe from there that all the old skool growers were wrong. Rootbound does not exist.
But seriously, how could so many be so wrong, for so long?
Then i got the opportunity to grow some real Landrace genetics. 100% sativa, straight from the wild. Pure animal cannabis.
I placed them into my customary 4" pots from seed and placed 1 in a 5" pot. They veg'ed fine and then flower came and they stretched right up to over 5ft. Then as each plant in the 4" pot reached 5'6" exactly the plant would quickly die. 1 by 1 the plants in the 4" pot would reach that critical height and then become unable to sustain themselves. However the 1 plant left in the 5" pot easily surpassed the 5'6" mark and was still growing fine when i killed it. I have no real room to be flowering 16 week sativas. Here is a pic of her just before death, standing around 5'10"

so what i was witnessing was not that the old skool were completely wrong... instead what i was seeing was simply cannabis adapting to an indoor and more restricted environment.
